Railroad switch stand having improved handle means

ABSTRACT

A railroad switch stand is provided for operating a railroad switch between two positions. The switch stand comprises a connecting rod connected to an operating mechanism for causing reciprocation of the connecting rod, and a handle connected to the operating mechanism for pivotal movement about a pivot axis between two operative positions. The handle has an open framework having an external configuration which is generally triangular in shape, with the apex of the triangle disposed at the inner end of the handle part where it is connected to a stub portion of the handle. With this configuration, the outer end of the handle presents a portion extending upwardly which can be easily grasped by a railroad personnel when it is desired to throw a switch.

BACKGROUND OF THE INVENTION

The present invention relates to railroad switch stands for operatingrailroad switches, and more particularly to manually operated switchstands which include a handle means in the form of a throwing leverwhich is usually formed of a heavy metal bar which may have a weight atthe outer end thereof. This type of switch stand is disadvantageousprimarily because a great deal of force is required to throw the switch.This has resulted in injuries of railroad personnel caused by actualthrowing of the switch. Such injuries are due to the heavyweight of thehandle means and are compounded by the necessity of bending over to anexcessive extent in order to grasp the handle means which is spaced onlya short distance above the ground.

SUMMARY OF THE INVENTION

According to the present invention, the prior art handle means of thelever type is redesigned enabling the operator to throw the switch withgreater ease and under safer conditions. The present handle is lighterin weight and its shape is such that in either of its two operativepositions, the handle means includes a portion which extends upwardly asubstantial distance above the ground to thereby minimize the amount ofbending required to grasp the handle.

The handle part of the invention is formed of a combination of solid andtubular metallic portions which provide the necessary strength whileslightly reducing the weight of the handle means. Such portions includea cross-member which rigidifies the structure of the handle means. Wearplates are also provided at the inner end of the handle structure toavoid undue deterioration each time the handle engages conventionallatch means at the switch.

The tubular and solid portions form an open framework having an externalconfiguration which is generally triangular in shape, with the apex ofthe triangle disposed at the inner end of the handle part where it isconnected to a stub portion of the handle means. With this construction,the outer end of the handle means presents a portion extending upwardlywhich can be readily grasped by railroad personnel when it is desired tothrow a switch. It has been found that the force required to operate aswitch stand according to the present invention is approximatelyone-half that required to operate a prior art switch stand having aconventional lever type handle means.

DESCRIPTION OF THE PREFERRED

Referring now to the drawing wherein like reference characters designatecorresponding parts throughout the several views, there is shown inFIGS. 3 and 4 a switch stand of conventional construction indicatedgenerally by reference numeral 10 and including a cover 12 and a bottompart 14 which is supported on pair of headblock ties 16 extendinglaterally outwardly of the usual railroad ties (not shown). The bottompart of the switch stand is connected to the headblock ties by aplurality of track spikes or bolts 18 which pass through suitable holesprovided through laterally extending flanges formed on die bottom part.

A conventional connecting rod 20 has one end operatively connected tothe switch stand in the usual manner, and the opposite end of theconnecting rod is connected to a railroad switch. The connecting rod isadapted to be reciprocated in opposite directions as indicated by arrowA, and is reciprocated in response to pivotal movement of the handlemeans indicated generally by reference numeral 22. The handle means isadapted to be latched in its two operative positions indicated in FIG. 3by full lines and phantom lines by conventional latch stands 24 and 26which are provided with foot pedals 28 and 30 respectively forselectively releasing the latch stands when desired to allow the handlemeans to pivot into a different operative position when desired. Latchstands 24 and 26 are supported on the headblock ties and are secured inplace by suitable studs 30 and 32 respectively which extend throughsuitable holes provided in the bases of the latch stands.

Referring now to FIGS. 1 and 2, the handle means of the invention isillustrated. The handle means includes a portion 40 formed of a heavymetal bar. Stub portion 40 is connected to a pinion shaft 42 having apinion gear 44 fixed to one end thereof. The pinion shalt is supportedfor rotation by the switch stand in the usual manner, and the piniongear engages a conventional segment gear of the switch stand. The handlemeans 22 is accordingly mounted for pivotal movement about a pivot axisextending longitudinally through the center of the pinion shaft 42.

The handle means includes an inner end indicated generally by referencenumeral 50 which is adjacent the pivot axis of the handle means. Thehandle means also includes an outer end indicated generally by referencenumber 52 which is disposed remote from the pivot axis. The inner end 50has a first dimension extending along an are having the pivot axis asits center, and the outer end 52 has a second dimension extending alongan are having the pivot axis as its center. The second dimension is manytimes greater than first dimension to define a handle means which is ofgenerally triangular configuration which can be clearly seen in FIG. 1.

The handle part which is connected to stub portion 40 comprises a pairof angularly related members 54, 56 which may be of one inch solid steelof either round or rectangular cross-section, as desired. Members 54, 56extend away from the pivot axis and diverge from one another. The handlepart further comprises a bent tubular member 58 which may be of one andone-quarter inch tubular steel having a bight portion 60, opposingessentially perpendicular sections 62 and 64, and legs 66 and 68 formingextensions of members 54, 56. Legs 66 and 68 are respectively telescopedover members 54 and 56 and welded thereto.

In order to rigidify the handle means, a tubular cross-member 70, whichmay be if one and one-quarter inch tubular steel, has the opposite endsthereof connected by welding to legs 66 and 68 adjacent to ends thereof.Gusset plates 72 are welded to cross-member 70 and legs 66 and 68, andgusset plates 74 are welded to cross-member 70 and 60 members 54 and 56,to enhance the rigidity and stability of the handle.

The inner end 50 of the handle means is provided with steel wear plates76 surrounding and welded to portion 40 and inner sections of members 54and 56, the wear plates serving to avoid wear due to abrasion whenengaging foot pedals 28 and 30 and the opposing stops as shown in FIG. 4when the switch handle is thrown between its solid outline and phantomoutline positions of FIG. 3.

A handle part of the switch handle according to the invention isfabricated to include an inner end having a pair of solid steel membersdisposed adjacent one another and diverging from one another in adirection away from die inner end to outer ends which are connected to atubular steel member having a tubular bight position thereby defining agenerally triangular configuration. A tubular cross-member is connectedbetween the legs of the tubular member at to rigidify the construction,and wear plates are fixed to the inner ends of the solid steel membersand to the steel portion to avoid undue wear od the switch handle duringoperation.

The invention has been described with reference to a preferredembodiment. Obviously, various modifications, alterations and otherembodiments will occur to others upon reading and understanding thisspecification. It is our intention to include all such modifications,alterations and alternate embodiments insofar as they come within thescope of the appended claims or the equivalent thereof.
